The TPS7A3501 is a positive voltage, low-noise
(3.8-µVRMS) power filter capable of sourcing a 1-A load suitable for
quiet supply solutions. Power filters, such as the TPS7A3501, provide voltage regulation across the
input and output terminals with high efficiency (low insertion loss), and power-supply rejection.
The device is ideally suited as a noise filter for 3.3-V, 2.5-V, and 1.8-V supplies at up to 1
A.
The input-to-output voltage regulation is also user-programmable, from 200 mV to 500 mV, with a single external resistor. If no resistor is used, the TPS7A3501 provides 330 mV of input-to-output voltage regulation. The device is stable with 10-µF input and output ceramic capacitors and a 10-nF noise-reduction ceramic capacitor.
The TPS7A3501 is fully specified over a wide temperature of –40°C to 125°C. The device is offered in a low thermal resistance, 2-mm × 2-mm, WSON-6 package. Unlike passive filters, the TPS7A3501 provides thermal and current protection for itself and surrounding circuitry.
